When I first saw this little fellow I thought of Balin - he seems the type to make sure everything is prepared before they set off. If you want to stay true to the book, it could be Dwalin, as he has a green cloak on (at least, it looks green to me!)

As for future suggestions, what might be nice (being bias just because I like you Dwarves ) is them huddled inside the cave in the Misty Mountains with thunder and lightning outside? You could paint any scene though and it would be great! Real talent demanon
